Proxmark3 v4.17768 Released

Version 4.17768 of the Iceman fork of the Proxmark3 firmware and client brings real-time low-frequency sampling, a flexible new standalone sniffer, smarter client reconnection, and a range of detection and stability fixes.

Highlights

  • Added real-time LF sampling on the device with the client receiving raw samples live, plus a bigger graph buffer and a trigger threshold option for capturing longer LF traces.
  • New hf_unisniff standalone mode is a 14a/14b/15 sniffer with runtime protocol selection and more save options, replacing the need to recompile for different sniff targets.
  • The client now auto-reconnects when the device goes offline: a background thread waits for the device, reconnects, and updates the prompt, removing the need to type hw connect on READLINE builds.
  • Implemented the Avigilon 56-bit format in the LF HID tooling, expanding access-control card support.
  • Reworked hf mf info with magic-card detection, static encrypted nonce detection, backdoor key checks for sector 0, and better Fudan version identification.
  • Added QL88 signature verification to hf 14a info, so QL88 tags are no longer misidentified as plain MIFARE Classic.
  • Added hf search hints across all HF protocols, including an iClass hint, making unknown card identification clearer.
  • Added a navigation slider to the plot window and improved data num to accept -r/-i flags for reversing or inverting values, alongside stack and memory hardening on the device side.
